Thanks Moon, I'm wary of things like green beans, because they can be a problem for some dogs. I have IBS and himself has IBD, so I can relate to your BIL, we both have different triggers from each other. I'm super cautious at this stage, because every flare up sets her back another step from recovery. I might mash some blueberries in once a day, see how she copes with them.
is there some kind of vitamin supplement you can add to that mixture? or maybe some kind of yogurt fortified with extra vitamins/minerals?
I have a vitamin paste, I haven't been able to try it because she is struggling with a flare up atm and it might make things worse for her. The vet has said that some vitamin tablets etc may actually irritate her, she's so sensitive atm.
Even the probiotic paste is an irritant for her, it is kaolin paste based but the oil in it set her off. I'm sprinkling human probiotic tablets over her food atm.
